SELF-VENTING FAUCE'I FOR BOTTLES.

To all whom it may concern:

Be it known that I, \VILLIAM E. Sornn, a citizen of the United States of America, residing at the borough of the Bronx, city, county, and State of New York, have invented certain new and useful Improvements in Self-Venting Faucets for Bottles, of which the following is a full, clear, and exact description.

This invention relates to an improvement in faucets, the object being to provide a faucet that is self-venting, that is to .say, so designed as to permit of the How of air therethrough when said faucet is attached to a receptacle for liquids, a bottle for instance.

It is a well known fact that liquids will not readily flow from a bottle provided with a faucet having a comparatively small opening, particularly if tilted substantially vertically. However, if air is allowed to enter the bottle in order to equalize the air pres sure, the liquid will flow therefrom.

The main object of my invention is to provide a faucet having one or more supplemental passages therethrough, whereby a plurality of passages is provided instead of the single discharge passage with which faucets now in use are provided.

Nhile my improved faucet can be used in connection with any liquid receptacle, I preferably use it in connection with bottles of the vacuum variety.

A vacuum bottle provided with my improved faucet can be put to various uses for which it is at present'not adapted; for in stance, a vacuum bottle can be filled with hot or cold liquid and secured to a suitable support in a vertical position, neck clownward. If at any time any of the contents of the bottle is desired the valve in the faucet can be turned on and the required quantity of liquid allowed to flow.

A vacuum bottle provided with my improved faucet could be locked in a cabinet and secured to the wall in a room of a hotel, hospital, car or other place, the faucet eX- tending through the cabinet. Thus secured, the bottle itself could not be stolen, but the contents could be drawn therefrom. At present a vacuum bottle could be not be used for such purpose. Furthermore, when the cork of a vacuum bottle is removed the ina frequent removal of the cork or cover will Specification of Letters Patent.

greatly affect the condition of the contents of the bottle, that is to say, if the liquid is hot it will more rapidly cool, and if cold will rapidly heat, especially in warm weather, at which time the bottle would naturally be used to keep the contents cold.

By the use of my improved faucet the contents of the bottle will not be exposed to the air,'excepting the small amount thatflows through the faucet into the bottle, and for this reason the bottle will more effectively perform its function.

I will now proceed to describe my invention in detail, the novel features of which I will point out in the appended claims, reference being had to the accompanying drawing, forming part hereof, wherein:

Figure 1 is a side elevation of a vacuum bottle, having my improved faucet applied thereto, the bottle being hung neck down; Fig. 2 is an enlarged longitudinal sectional view of my improved faucet shown integral with a bottle cap, a portion of a bottle being also shown; and Fig. 3 is an enlarged crosssectional view thereof, the section being taken on a line aa in Fig. 2.

Referring to the drawing, my invention comprises a faucet consisting of the body portion 1, provided with a rotary valve 2 and a cap 3, provided with threads 4. The cap 3 is shown as formed integral with the body portion 1 of the faucet, but maybe a separate member and secured to said faucet in any desirable manner. The threads 4 on the cap 3 engage the threaded neck 5 on the end-member 6 of a bottle 6*. The bottle 6, herein illustrated, is of the vacuum variety, within which liquids are maintained, hot or cold. As this form of bottle is well known no further description of the same need be made.

To adapt the faucet for the purpose for which it is designed I provide the same with a centrally located longitudinally disposed opening or passage 7, which communicates with the interior of the bottle and permits of the escape of liquid from the said bottle. In order that air can force its way into the bottle and thereby equalize the atmospheric pressure, I provide the body portion 1 of the faucet with air passages 8, which are placed adjacent to the discharge passage 7 and which are also disposed longitudinally of the body portionl of the faucet and which also communicate with the interior of the bottle. In this instance, the air passages 8 are formed by the partitions 9 (see Fig. 3) which connect the outer wall of the body portion 1 and wall 10 around the discharge passage 7.

To insure an air-tight connection between the cap 3 andbottle (S I provide the said cap with a gasket 11, which may be made out of cork, rubber or any other similar material. The gasket 11 contacts with the neck 12 of the interior receptacle of the vacuum bottle. The gasket 11 is forced against the neck 12, when said cap is screwed home upon the neck 5 of the end 6 of the bottle.

Should the bottle be positioned as shown in Fig. 1, or, in other words, secured to a support 14 by means of the straps 15, the neck of the bottle pointing downwardly, the contents thereof may be withdrawn at will. hen the valve 2 is rotated to open the passages 7 and 8, or rather to place the interior of the bottle in communication with any receptacle that may be placed under the faucet, air will force its way into the interior of the bottle through the passages 8, and the liquid in the bottle will flow through the dis charge passage 7 The openings of the passages 8 are made smaller in area than the discharge passage 7 in order that the liquid will not flow therethrough to any great extent. In Fig. 3 the passages 8 are illustrated much larger in proportion than they would be in practice.

To retain the gasket 11 in position, I preferably provide the cap 3 with a neck 13, which passes completely through the gasket 11.

It will be apparent that my improved faucet and cap combined, constitute a bottle closure, which is particularly adapted for vacuum bottles.

Copies of this patent may be obtained for Having now described my invention, what I claim and desire to secure by Letters Patent is:

1. A bottle closure, comprising a cap, a body portion carried by said cap, the body portion having an interior tube extending longitudinally thereof, providing a central passage, a plurality of radially disposed partitions connecting the wall of said tube and the wall of said body portion, said partitions extending substantially throughout the length of said tube, whereby a plurality of passages are provided exteriorly of the central tube, and a valve to close said passages.

2. A bottle closure, comprising a cap, a faucet integral with said cap, comprising a body portion provided with a central passage extending longitudinally thereof, a neck carried by said cap and provided with a longitudinally disposed central passage in alinement with the central passage in said body portion, a circular wall in said body portion surrounding the central passage therein, said wall extending through said neck, and a plurality of radially disposed partitions connecting said circular wall and the wall of said body portion and said neck, said partitions extending throughout the length of said circular wall whereby a plurality of passages are provided, a valve carried by said body portion provided with an opening adapted to aline with the passages in said faucet, and a gasket located within said cap.

Signed at New York city, N. Y., this 8th day of March, 1912.
